Containerizing a Simple Django Application with Docker and Docker Compose

We’ll create a Dockerfile in order to containerize a Django app and we’'ll set up docker-compose through a docker-compose.yml file.

If you’ve been coding for a while now, you probably have heard of Docker or more fancy terms like containers. This article introduces you to the concept of containerization with Docker while guiding you to containerize a simple Django web application. At the end of this topic, you should be familiar with the following:

  • Virtualization
  • Containerization (using Docker)
  • Docker
  • Writing a Dockerfile
  • Docker compose
  • Setting up a Django app in a docker environment using a Dockerfile and docker-compose

Requirements

To follow along with this tutorial, it is recommended to have the following installed on your computer:

  • Git / GitHub
  • Visual Studio Code (or any text editor of your choice)
  • Working knowledge of Django

Containerized Applications and Deploy Simple Application on Docker

If you are a software engineer, you must know where your application is deployed. A few years back, web applications were deployed on dedicated physical servers. The evolution of application deployment can be considered as three generations. Let’s explore it for your knowledge.

Generation 1 — Dedicated Physical Servers

Earlier days, the application was deployed in a dedicated physical server. You may think that nowadays also deployed on physical servers. But it was a different story. For example, if your application needs to have different servers like the application server, database server, mail server, and web server, you must have four different hardware boxes (physical servers) to deploy this application.

There are many disadvantages of these servers.

  • Space for servers (Server room)
  • Maintenance cost (air-conditioned room, security, service)
  • Separate network
  • Operation systems
  • Resources waste (servers are not used 100% of processing power/ memory)

How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

Run multi-container Docker applications with a single command

What is docker?

Docker is a platform to develop, deploy, and run applications inside independent and isolated environments. These environments are then called containers. This will let the developer run a container on any machine.

Simply docker solves the problem of **‘’It works on my machine’’**.

As you can see, with Docker, there are no more dependency or compilation problems. All you have to do is launch your container, and your application will launch immediately.

If you want to learn more about this excellent platform, the “Get Started” section of Docker Docs is a great place to start.


Let’s move onto the topic.

If your application is containing more than one component (multiple containers), how do you manage such a situation easily? It means you need to run those multiple containers separately. How do you manage their network connectivity, volume binding, port binding, etc. from a central point?

When using Docker widely, the management of several different containers quickly becomes cumbersome.

Introducing docker-compose

Docker Compose is a tool that helps us overcome this problem and efficiently handle multiple containers at once. Also used to manage several containers at the same time for the same application.

This tool can become very powerful and allow you to deploy applications with complex architectures very quickly.
